While London's 'taxi wars' have hit the headlines in recent weeks, Addison Lee is exploring plans to expand beyond the city to other UK regions. The company currently operates more than 3,500 cars, in a market that features black cabs and newer services such as Uber and Hailo.

"It’s an exciting time to be operating in the highly competitive private hire space, making this a great win for W," said W founder Warren Johnson. "Addison Lee is the biggest player in the sector, and we are looking forward to working together to build the brand and find new ways to connect with its loyal fans."
